High winds caused by Storm Doris have been causing lengthy delays and some cancellations to trains between Hemel Hempstead, Berkhamsted, Tring and London.
London Midland is advising customers not to travel today, wherever possible. Trains are subject to a 50mph speed restriction across the network until at least 4pm, with journeys particularly on services to/from London Euston and towards Liverpool and Crewe needing to travel at a slower speed.
Trains that have been delayed from London Euston, that were scheduled to stop at Hemel, include the 16.05, 16.34 and 16.54 services.
Others are also being delayed due to the high winds and speed restriction, along with debris on the track.
